Как вы можете видеть на java, переменная mAddressEditing
получена из намерения, когда она не является нулевой, это означает, что пользователь хочет изменить свой адрес.
Все поля заполняются так, как ожидалось, однако, когда я нажимаю на текст редактирования, чтобы изменить его значение, это сбой...

Я понятия не имею, почему он рушится.
Шаги для воспроизведения: 1. Отредактируйте адрес из предыдущего экрана, передав объект Address в качестве параметра в намерении 2. Нажмите на текст редактирования, чтобы изменить его значение. 3. Сбой!
